What This Workflow Does

This automation runs every hour to process your ad queue systematically:

• Downloads image and video assets from Google Drive using URLs, file IDs, or filenames
• Uploads media to Meta Marketing API and builds creative assets with optional custom video thumbnails
• Creates ads in PAUSED state within your specified campaign and ad set
• Updates the Google Sheet with ad IDs, status, and any error messages
• Sends confirmation and error notifications directly to your Slack channel
